Add the bedroom, bigger kitchen or family room you need, with a layout that connects naturally to the rest of your home.
Give parents or adult children a place of their own, with space to be together and privacy when they need it.
Explore a separate rental suite as part of your addition, where permitted. Check the property, approvals and build costs before relying on that income.
See the layout in 3D and review an itemized fixed quote before you sign. Agree on changes before extra work begins.
Open up the main floor for a bigger kitchen or family room. The lot and setbacks determine how far you can extend.
Add bedrooms upstairs without extending farther into the yard. The foundations, framing and stair layout need checking first.
Add space beside the house or above a garage where the property allows. Check structure, access, parking and windows together.
Add space where one room feels tight. Compare the structural work and cost before assuming a smaller addition is simpler.
Concept illustrations. Copper shows added space. Hover or tap the house to see the original home.
Plan basement living space, an office or a separate suite around the intended use. Rental use needs its own design and approval path.
Review the structure, access and permitted use before adding a garage or changing how an existing garage is used.
Plan a sunroom around the connection to the existing house, the lot and the way you want to use the extra space.
Add upstairs rooms where the existing structure and property allow. Check foundations, framing and the stair layout before developing the design.
Plan room connections, structural work and services together before opening walls or changing the main-floor layout.
Bring the deck, patio or covered outdoor space into the plan alongside its connection to the house.
Plan floor levels, windows, roof connections and services together, so the extra room works with the house you already have.
Review our current liability insurance and WSIB documents before construction begins.
Our lifetime workmanship warranty is written and transferable. Review its coverage and terms alongside your agreed scope.
Agree which rooms stay usable, how work areas are separated and when water or power may be interrupted.
These completed whole-home renovations show connected kitchens, living spaces and finishes. At your visit, ask how comparable structural work would apply to your house.

A planning reference, not a Capable price list.
Drawings, engineering, permits and HST are outside that construction starting point. Confirm what the free design-and-drawings offer covers for your project.
Foundations, roof connections, new kitchens or bathrooms, service upgrades and work in the original rooms. We review those connections before preparing your itemized fixed quote.
All prices in Canadian dollars, before HST unless stated.
Property: Check the lot, existing structure and where the new rooms will connect before developing the layout.
Price: Separate included work, allowances and anything that needs further investigation in the quote.
Changes: Review the price and schedule before approving extra work.
Bring any survey, drawings or existing proposal you have to the free visit.
Your schedule needs to cover approvals, construction and the days your household will be affected. Open the questions below to see what to agree before work begins.
Start with the rooms you need and the way you use the house. Check the footprint, structure and likely approval route before detailed drawings, so the design follows what the property can support.
Show how the addition joins the house, including structure, stairs, roof and services. Resolve open layout decisions before the permit application and construction schedule are finalized.
Toronto lists a 10-business-day review standard for complete, eligible House Stream applications. That is a review period, not a permit-issuance promise. Drawings, zoning and applicable-law requirements come first. Comments, revisions or other approvals can add time. Residential additions do not qualify for the three-day Express review goal.
The build moves through foundations, framing, weather enclosure, services and finishes. Before starting, agree when the house will be protected from weather and which rooms or services will be interrupted. What can change dates: Engineering revisions, municipal comments, weather, access and material lead times can change the schedule. Confirm dates against the agreed scope and remaining dependencies.
Sometimes. Structural openings, weather exposure or utility interruptions may make a temporary move necessary. Before construction, agree which rooms remain usable, how crews and materials enter, and how dust and work areas will be separated. Include any move-out period in your household budget and schedule.
Compare what the addition solves with its complete cost and disruption. Include changes to the existing rooms and any temporary accommodation. The right layout can improve daily life, but a resale gain or rental return is not guaranteed. Choose the scope because it fits your needs and budget.
Walk through the house and the space you need. Bring any survey, drawings or existing proposal you already have.
See the layout, review the work and price, and clarify allowances, exclusions and required approvals before you sign.
With required approvals in place, we coordinate construction and finish with a walkthrough of the agreed work.

A rear addition can enlarge the main floor; a second storey can add upstairs rooms. A side or garage addition depends on access, parking and structure. Start with the space you need, then check the lot and existing house. A smaller bump-out or a revised layout may solve the problem with less work.
Ask for included work, allowances and exclusions separately. Check design, drawings, engineering, permits, foundations, framing, roof, services, finishes, protection, disposal and HST. Include changes to existing rooms. A square-foot rate is a planning reference; your fixed quote needs an agreed scope and site review.
Check the survey or site plan, zoning, setbacks, height, lot coverage, trees, drainage, structure and services. Toronto requires drawings showing the existing house and proposed addition. A neighbour’s addition does not establish what your property allows. Identify missing information before developing detailed drawings.
These are separate stages. Toronto’s 10-business-day House Stream standard applies to complete, eligible applications and is not a permit-issuance promise. Additions are outside Express review. Design revisions, municipal comments, materials and structural work affect the total schedule. Agree construction dates when the scope and outstanding requirements are clear.
Sometimes, but structural openings, weather exposure and interruptions to water or electricity can make rooms unusable. Agree which rooms remain available, how the work area is separated and whether a temporary move is needed. Put those arrangements in the schedule before construction starts.
Resolve the footprint, foundation, roof and service requirements before choosing custom finishes. Keep inclusions, allowances, exclusions and unresolved conditions clear. Review the price and timing of changes before approving work. Budget for uncertainty that remains after the site review; a contingency does not replace a complete scope.
It may, but neither a resale gain nor recovery of the full construction cost is guaranteed. Consider the added space, layout, neighbourhood and complete project cost. If rental income is part of the plan, check whether a separate unit is permitted and assess the costs before relying on that income.
Ask who coordinates drawings, engineering and permits; what the quote excludes; and how the house will be protected during structural work. Request current insurance, WSIB documents and relevant addition experience. Agree who answers questions and how scope, price or schedule changes will be approved.
For GTA planning, 500 sq ft at the existing $350–$550 per sq ft market range is about $175,000–$275,000 for construction. This is not a province-wide price or a Capable quote. Budget separately for drawings, engineering, permits and HST; kitchens, bathrooms and structural connections can change the scope.
First check whether a better layout or existing unfinished space can meet the need. If you need a larger building, compare addition options on the same complete scope. A smaller footprint can reduce area, but foundations, roof connections and services can still make a small addition substantial work.
Major structural work can be a large share: footings, foundations, steel and framing, or roof removal and reinforcement for a second storey. Kitchens, bathrooms and service upgrades add other costs. The largest item depends on your house, so compare the itemized scope rather than assuming every addition costs the same.
That needs a structural assessment of the footings, foundation walls and framing. A first visit can identify questions to investigate; it cannot replace the engineering needed to confirm capacity. Establish any reinforcement work before treating the upstairs layout or construction price as settled.
Compare the full addition budget, including changes to existing rooms and temporary accommodation, with buying another home and the costs of selling and moving. The answer depends on your property and the home you would buy. Include the value to you of staying in your neighbourhood; neither option is automatically cheaper.
You may need a minor variance if the proposal does not meet zoning rules such as height, setbacks or floor area. A compliant design may avoid that step, but building-permit and other applicable requirements still remain. Confirm the route for your property before relying on a start date.
